Patent KR-860000278-B1 (KR)
Title: Bogie truck for railroad car
Inventor: POLLARD MAURICE G
IPC: B61F5/38
Filed: 1980-09-04
Granted: 1986-03-26
Abstract: A motorized vehicle truck has a pair of wheel sets, each with a live axle and a motor mounted on each axle, with their axies paralled to the associated axle. Each motor is secured to prevent its rotation about the respective axle. This permits unrestrained horizontal movement of the motors relative to the truck, so braces are employed in the form of at least one link which is connected between the respective motor casing and pivotally, resiliently mounted for rotation about a vertical axis positioned between the motor casings. In this way, suitably stiffness is provided through the motor casing to restrain parallel shear movement of one wheel set horizontally relative to the other.
Patent KR-830002630-B1 (KR)
IPC: H03K17/13
Filed: 1980-09-13
Granted: 1983-12-06
Abstract: In carrier and timing recovery systems for high performance data modems it is essential to employ threshold comparators and to be able to determine accurately zero-crossing instants. The circuit of the invention comprises a comparator with feedback which produces a positive transition of the comparator output in response to the negative zero-crossing transition of the input signal on condition that the previous half-cycle of the input signal has exceeded the positive reference threshold. In a practical arrangement two comparators are provided together with a pair of bistable storage elements which produces a narrow pulse in response to the negative zero-crossing transition of an input signal provided that the input signal has exceeded the positive reference threshold applied to the second comparator.

Title: Method and apparatus for producing a liquefied permanent gas stream
Inventor: MARSHALL JOHN
IPC: F25J1/02
Filed: 1985-07-20
Granted: 1994-01-28
Abstract: A stream of permanent gas such as nitrogen at elevated pressure is cooled to below its critical temperature by heat exchange with work-expanded working fluid. The stream 2 is then further cooled in heat exchanger 4 and successfully flashed through at least three expansion valves 6, 12 and 16. Resulting flash gas is separated from liquid gas in separators 10, 14 and 18 respectively. The flash gas is passed through the heat exchanger 4 to provide cooling for such heat exchanger. By performing at three such successive isenthalpic expansions instead of the conventional one or two expansions, greater thermodynamic efficiency can be achieved enabling more favourable conditions to be set for the work expansion of the working fluid.

Abstract: 프린트 기판 조립장치는 프린트 기판이 기판베이스 상에서 유지되는 백업핀에 의해서 지지되는 장착테이블을 포함하고 있다. 장착테이블은 X방향으로 이동가능하며 전자부품을 프린트 기판 상에 장착하기 위한 장첵헤드는 Y방향으로 이동가능하다. 백업핀 스토커는 사용되지 않는 예비 백업핀을 저장하는 기판베이스 근처에 제공된다. 교환수단은 기판베이스와 백업핀 스토커 사이에서 장착헤드와 함께 이동가능하도록 장착헤드에 부착되어 조립될 프린트 기판에 변화될 때 기판 상에서 유지된 백업핀이 프린트기판 타입등의 대표적인 데이터를 기초하여 백업핀스토커 내에 저장된 백업핀으로 교환수단에 의해서 전환될 수 있다.

Abstract: Novel chromium-containing compounds, such as, for example, chromium pyrrolides, are prepared by forming a mixture of a chromium salt, a metal amide, and an electron pair donor solvent, such as, for example, an ether. These novel chromium-containing, or chromium pyrrolide, compounds can be used either unsupported or supported on an inorganic oxide support to trimerize and/or polymerize olefins.
